Reverse Alpha Blending

Alpha compositing formula: C_out = α·W + (1−α)·C_orig. We invert it: C_orig = (C_out − α·W) / (1−α) to recover original pixels beneath the watermark layer.

🧩

Patch-Based Inpainting

After alpha reversal, a bilateral-weighted neighborhood inpainting pass blends residual artifacts away using surrounding pixel statistics for seamless healing.
